Edo Glass is a soy sauce dish made in the traditional method.
Iwasawa Glass started manufacturing glass in the Koto-ku since 196 and was temporarily interrupted by a company during war and resumed in Sumida City in 1965. Each product is hand made according to the tradition of "Edo Glasses" under two traditional craftspeople in Tokyo. Originally produced mainly lenses (car and motorcycle lights) and oil pours (screw outs) but now we offer a wide variety of glassware including tableware, vase, paperweight, trophy and more.
